Abstract

Due to the limited movements possible in a restricted, bed-ridden position, conventional bedside furniture can be difficult to use. Patients are often at a loss for where to place items such as tissues, thermometers and portable radios. In order to improve this situation, working area and field-of-view in the supine position were measured for 10 male and 10 female subjects. Suitable positions for placing such necessities existed within the area framed by the arcs described by the fingertip and wrist as the upper limb was abducted from 30° to 70°. The height of the surface for placing objects should be adjustable from 150mm to 200mm above the bed surface. Based on these limitations, a cabinet (300mm wide×200mm deep×250mm high) was designed to move on a rail and rotate around a stem with an eccentric center, so that it could be available at a suitable location and moved smoothly out of the way as necessary. With these features, the developed cabinet is “user-friendly” for bed-ridden individuals and does not interfere with care activities or conventional furniture. Assisting self-support during periods of bed rest, the cabinet was highly regarded by patients, nurses and medical staff during trial use.
